VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 320,251, dated June 16, 1885'.

Application filed June 13, 1884. (No model.)

To all whom it may concern.-

Be it known that I, REINHoLD E. HEN- NINGES, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a new and useful Improvement in Ventilators, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specitieation.

This invention relates to ventilators which are to be attached to window-sashes; and it consists of the construction and arrangement of parts hereinafter described.

in the drawings, Figure 1 is a partial view ot'a window-sash. showing my invention. Fig. 2 is a cross-section of the same, and Figs. 3 and 4 are detail views in perspective.

A indicates the upper sash of a window, and B is a recess cut in the upper edge ofthe sash. This recess, which extends through the sash from the outside to the inside, is preferably from one-half an inch to an inch deep and from eight to eighteen inches long.

To the outer side of the sash is secured a cast-iron frame, 0, which partially tits in said recess, and is provided with a pivoted valve, D, which is adapted to close a horizontal opening, E, in the frame.

The valve is provided at its middle and on its inner side with a projection, F, and is pivoted on the outer side of its vertical plane, which serves to hold the valve in a vertical posit-ion to close said opening.

To projection F are attached both ends of'a cord, G, for operating the valve.

On the inner surface of the frame 0 is supported a roller, H, over which one end of the cord G is passed before being attached to the projection F.

\Vith this construction and arrangement the valve will be closed by pulling on one strand of the cord and opened by pulling on the other. The weight of the valve will hold it open, or, when desired, will hold it closed.

To the inner side of the sash is secured a guard. I, consisting of a curved plate, which partially tits in the recess B,and has its lower and inneredge extended down in front of the recess to deflect the atmosphere downward as it enters the room, and also to form a kind of flue for creating an upward current for the escape of impure air.

I do not claim, broadly, a weighted or gravitating valve for controlling passage of air currents; nor the use of cords for opening or clo ing an air-valve; nor a curved deflector for governing the direction of air-currents, for I am well aware these are not new.

\Vhat I claim is 1. In a window-ventilator, the combination, with the metal frame 0, having a slot and adapted to be set in a recess of the windowsash, ofthe valve D. which is pivoted at its lower edge and provided with the arm F, projecting rearwardly through said slot, and the cords extending back through said recess and down the inner side of the window, as shown and described, to operate as specified.

2. In combination with the recessed window-sash and the valve D, pivoted on one side thereof, the deflector I, which is attached on the opposite side of the sash and curved downward, as shown, and the valve-operating cords G, which extend through said deflector and recess, and are thus made accessible on the inner side of the window, as shown and described.
